Cleaning/Removing Corrosion from Cast Aluminum Parts

How do I clean the corrosion from an aluminum motorcycle brake hub part? The part in question is cast and machined aluminum, about 8 inches in diameter, with lots of nooks and crannies. It's covered with corrosion as if were left outside for a time in a damp place like Florida (which it was).

Try this recipe(from one German book):
1 lit water
10-40 gm sodium carbonate / washing soda [affil links]
5-10 gm 'water glass' [on eBay or Amazon] temperature 60-90 °C; after cleaning rinse well!
